-- Locked Stuff for Home Decor mod, by Kaeza
-- 2013-02-19

-- The code is mostly copypasta from default:chest_locked, with a few
-- tidbits to ease creation of new items, should need arise.

| create_locked ( name, infotext )
|
| Description:
| This function takes a base node name such as "homedecor:refrigerator",
| copies the definition from the original item into a new table, modifies
| it a bit, and registers a new node with a "_locked" suffix such as
| "homedecor:refrigerator_locked". The new node behaves identically to
| the base node, except that moving items to/from the node's inventory
| is only allowed for the original placer. In addition, it register a new
| shapeless recipe for the node, using the base node plus a steel ingot.
|
| Arguments:
| name The base node name
| infotext The infotext description (in case the name is too long).
|
| Example Usage:
| create_locked("homedecor:refrigerator", "Locked Fridge")
| ^ This generates a new "Locked Refrigerator" node, whose infotext is
| "Locked Fridge (owned by <placer>)".
|
| Notes:
| If <infotext> is not specified (or is nil), the infotext will be the
| base node's description prefixed by "Locked ".
